#1 - Amygdoloidal Basalt matrix with Thomsonite nodules(?), found north of Duluth, MN. It is about 6 inches x 4 inches x 3 inches tall. Weighs 4 lbs. 2.7 oz. There are purple crystals in the center of the pinkish/white area in the first photo. There are shiny crystals (?) in the other holes as well. The last photo shows it wet. I will be listing several similar rocks. I think that this is what they are, but I'm new to Rock Hounding. If anyone has any other ideas I would welcome info.

I will combine shipping & will reimburse any over payment of shipping costs over $ .50. You could get a bunch of rocks in this box! I will ship small flat rate, so it will be $7.15 to continental U.S. Anyone else please contact me for a shipping price.
